In
http://www.w3.org/TR/REC-CSS2/visufx.html
the text
"In CSS2, the only valid <shape> value is: rect (<top> <right> <bottom> <left>)"
appears. This clearly indicates that white space is permitted (and perhaps required)
between "rect" and the open parenthesis "(". However, Netscape 7.1 does not permit
white space here, and a note at
http://www.webfrustration.com/showthread.php?threadid=141274
from Thomas 'PointedEars' Lahn
"It needs to be `clip:rect(0 auto auto 280px)' (without whitespace after
the `rect' ... "
also indicates that white space is not permitted. Could the W3C please rule on
this and indicate whether white space between "rect" and the open parenthesis
is (a) required, (b) optional, or (c) disallowed. If (c), could I please ask
that a future revision change this to (b) [optional]
